Resources to Supplement Strategies
1. Methods of Delivery:
A teaching strategy is defined as “a combination of
student activities supported by the use of
appropriate resources to provide a particular
learning experience (process) and or to bring about
the desired learning (product)”.
Notice, in the definition, the emphasis is placed
firmly on the needs of the student not on the
teacher.
Some of the popular strategies are:
 Lecture
 Case Study
 Question & Answer
 Role Play
 Group Discussion
 Project
 Practical
 Assignment
 Tutorial
 Problem Solving
 Individual Learning
 Demonstration
 Seminar
Practical:
Real or simulated (pretend to have or feel)
situations with student learning from
experience.
Demonstration:
Teacher shows the basic steps and sequence
of a skill, or the main attributes of a concept,
with student watching.
Discussion on a basic topic
“Ohm’s Law”
Theory:
Current flowing through a circuit is directly
proportional to the voltage applied across the
circuit and inversely proportional to the
resistance of the circuit in a certain
temperature.

▪ What is the Conception (an idea or mental picture
of a group or class of objects formed by combining
all their objects) of this theory ?
▪ Perception: (the ability of mind to refer sensory
information to an external object as its cause)
▪ To take perception let us do a Laboratory or Practical
or Experiment.
Subject Name:
Experiment No:
Name of the Experiment: Ohm’s Law (or Verification of
Ohm’s Law)
Objectives: 1. Verification of Ohm’s Law

Knowing the connection of ammeter &
voltmeter in the circuit
Required equipment & Materials:
1.
Ammeter (dc 0 – 1 amps)
1 no.
2.
Voltmeter (dc 0 – 30 volts)
1 no.
3.
Resistances (50, 200 ohms)
1 no each
4.
Power supply unit (dc 0 – 30 volts)
1 no.
5.
Wire
as required
Procedure:
1.
Collect all the equipment & materials
2.
According to the circuit diagram drawn below connect
ammeter, voltmeter and resistance to the power supply unit.
Ensure that ammeter connection with the load in series and
voltmeter in parallel. Use right polarity in the connection of dc
meters.

3. Connect 200 Ω resistance in the circuit and then supply the
voltage. Take ammeter and voltmeter reading precisely and
then record in the data table given below.

Increasing the supply voltage and then take 4/5 readings of
ammeter and voltmeter.
Repeat 3 & 4 points for 50 Ω resistance.
Draw V – I curve taken data from the data table in the graph

Is there any changes of the current when changing voltage
for 200 Ω resistance?
Is there any changes of the current when changing
resistance when keeping voltage constant?
3.
Is Ohm’s Law verified by This experiment? Mention it.
4.
If 1 amp current flows through 100 Ω resistance then
(a)
What is the supply voltage ?
(b)
For the same supply voltage what is the current for
50 Ω resistance?
Worksheet:
A worksheet is an incomplete handout
which the student is expected to
complete during or straight after the
lesson. They can be used by individual
students for individual attention. They
allow students to work at their own pace,
in an independent manner.
There are several types of worksheet:
1.
Job sheet: which contain instructions or
specification so that a student can complete a piece
of work.
2.
Operation sheets: are used to explain a process
or series of operations e.g. How to take blood
pressure or how to operate a photocopier etc.
3.
Assignment sheet: usually consisting of a number
of questions, problems or tasks to be performed.
4.
Experiment sheet: frequently used in laboratory
work.

Teacher’s Responsibility
Group size should be small preferably 2 (two).
Ensure that all students can participate actively.
Ensure health and safety.
Assist each group.
Guiding groups of students but not telling them every
thing.
Ensure student perception either by worksheet or by
conclusion (written by student).
Ensure feedback by returning back to the learner.
Learner’s Responsibility
• Working at own pace.
• Learning from each other by pooling
knowledge.
• Learning and displaying group skills.
• Working at the pace of the group.
• Seek assistance from your teacher if needed.
• Take care for delicate and dangerous
experiment.
